Semantic Web Services Discovery System with QoS for Enhanced Web Services Quality
نویسندگان
چکیده
Semantic Web Services are the key technology providing services for the users’ convenience in the semantic web environment. Many companies in various fields are researching and developing languages for constructing Semantic Web Services such as DAML-S, WSDL, X-LANG and BPEL4WS. DAML-S is a method that accesses the existing Web Service method from a semantic web environment. However, the current Semantic Web Services Discovery System does not provide sufficient processing of quality factors (performance, accessibility, availability, reliability and transaction) nor reliable and accurate service results desired by the user through a UDDI search method. The present study analyzes the disadvantages of the current web services and suggests a Semantic Web Services Discovery System based on QoS applying semantic web technologies as a solution to the problems. The suggested system provides a UDDI and DAML-S based discovery engine to allow efficient web service discovery and composition.

In general, Policy-based approaches play an important role in the management of web services, for instance, in the choice of semantic web service and quality of services (QoS) in particular. The present research work illustrates a procedure for the web service selection among functionality similar web services based on WS-Policy semantic matching. In this study, the procedure of WS-Policy publi...

Quality of service (QoS) is an important issue in the design and management of web service composition. QoS in web services consists of various non-functional factors, such as execution cost, execution time, availability, successful execution rate, and security. In recent years, the number of available web services has proliferated, and then offered the same services increasingly. The same web ...

Since, most of the organizations present their services electronically, the number of functionally-equivalent web services is increasing as well as the number of users that employ those web services. Consequently, plenty of information is generated by the users and the web services that lead to the users be in trouble in finding their appropriate web services. Therefore, it is required to provi...
متن کاملSemantic and QoS based Web Service Selection using a Multi Agent System
Currently all web services are published and found by making use of the WSDL and UDDI techniques. This forces the consumers to find and bind services at design time since WSDL relies on static descriptions. Also the current techniques don’t address runtime service selection based on a dynamic assessment of QoS attributes. Hence in this paper, a Semantic QoS Web Services Agent Framework (SQoSWSA...
